I've been using my "82" for a little over one year now. Up until this week I've absolutely loved it. But all of a sudden I'm having a problem with the " i " key. Either it doesn't work at all or, alternatively, it will type two i's. I haven't spilled anything in it and iit's in a fairly clean environment. Anybody else having a similar problem and have a fix suggestion? Help!

The problem generally occurs because excessive debris has made its way between the key switches contact points. Replacing the key switch will work but may not be the most convenient fix as it requires soldering/desoldering. You could try washing your board, see the following posts for some ideas:
